"Enable drag and drop text editing" can be checked on the Interface tab 
of preferences.  (Apparently this feature has been available since 
version 3 but I did not know about it.)

I think that this is useful (and it would be an order of magnitude more 
useful if it worked across applications [on Windows], e.g. for dragging 
code to the FE from a browser!), but it has some usability problems that 
even make it slightly dangerous:

First, undo does not work with drag and drop.  It removes the dropped 
object but it does not replace it to its original location (so the 
object is practically deleted).

Second, when dragging something over a graphic, it completely replaces 
the graphic.  Maybe it would be better to disallow dragging objects over 
graphics.
